His condition is called "enuresis."
The word enuresis is gotten from a Greek word (enourein) that signifies "to void urine." It can happen either amid the day or during the evening (however some limit the term to bed wetting that happens around evening time). Enuresis can be separated into essential and optional structures. Essential enuresis is characterized as the patient never having been dry; optional enuresis is characterized as the patient having had a time of being dry and after that beginning to wet.
